SPECIFICATION forming part of Letters Patent N 0. 642,065, dated January 30, 1900.

Application filed February 18, 1899. Serial No 705,947. -(No model.)

To aZZ whom it may concern.-

Be it known that I, RICHARD BANKMANN, a citizen of the United States, residing at IVashington, in the District of Columbia, have invented certain new and useful Improvements in File-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 0thers skilled in the art to which it appertains to make and use the same.

This invention relates to holders for files and other papers of that class in which a follower and a clamp sliding in a groove in the base-board are used; and it consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 is a perspective of my improved file-holder; Fig. 2, a transverse section of the base-board; Fig. 3, an end view of the same; Fig. 4, a like view of the head-block detached; Fig. 5, a perspective of the same; Fig. 6, alike view, partly in section, of the base-board and the guideplate in the slots in the base-board, part of the baseboard being removed, and on an enlarged scale; Fig. 7, a like view showing a modification of the guide-plate; Fig. 8, a like view of one of the guide-plates shown in Fig. 6, on an enlarged scale; Fig. 9, a side elevation of the follower and the clamp and a section of the base-board, showing the clamp thrown over the end of the base-board; Fig. 10, a perspective of the clamp detached; Fig. 11, a top plan of the upper end of the clampbar, and Fig. 12 an elevation of the lower end of the clamp-bar.

Reference being had to the drawings and the letters thereon, A indicates the front of a file-holder; B, the base-board; O (J, the sides, and D the follower.

As at present constructed the base-board splits, the guide-plate spreads and releases the clamp and not infrequently splits in releasing it from files, and in either event the holder is seriously damaged and requires repairing. It is my purpose to overcome the serious defects enumerated, and to this end the guide-plate, which consists of two parallel plates a a, bent at an angle, so that the top is approximately horizontal and the side at an angle of about forty-five degrees thereto, is provided with rigid teeth I) on the edge of the angular sides, which are cut out of the metal and forced back or down and form two shoulders c and d at right angles to each other, and intermediate the teeth and on the opposite side of the plate may be formed projections 1) by indenting the metal, which also serve to secure the plates in the slots 6 e by embedding in the baseboard. As the guideplate is driven into the angular slots 6 e on opposite sides of the groove E in the baseboard the teeth embed themselves in the wood and prevent the plates a a moving laterally in either direction, thus preserving the slot f between the plates of the predetermined width and rendering it impossible for the clamp to he accidentally released from the base-board. These teeth also prevent the guide-plate from being moved longitudinally, and thereby do away with the tail-block generally used at the inner end of the guide-plate and secured by the front of the holder. The teeth I) and the projections I) cut their way into the base-board, and after the guide-plate has been driven into the angular slots 6 c it is immovable.

In Fig. 7 is shown a modification of this construction and in which the plates 06 a are provided with a narrow right-angled projection 9 along the inner edge of the plate,which cuts its way into the baseboard and performs the same functions as the teeth.

F is the head-block, which is inserted in the groove 6 in the end of the base-board and is provided with studs t' 2', by which the plates (1 are secured thereto by riveting the studs, and on each side of the head-block are laterally-extending arms 7o 70, on whose upper surface are projections Z l, inclined on their up per faces or ends and on their inner sides to embed in the base-board and draw toward the center, thus resisting the tendency of the base-board to warp or split through the groove E, which is the Weakest part of the base-board. The inner side of the head-block is curved, and its upper surface m is cutaway and a transverse groove k formed in the upper surface of the head-block to admit of throwing the follower I) back out of the way when the file-holder is in the position shown in Fig. 9.

On the back of the follower D is secured a clamp-plate G, which is made nearly as Wide as the follower to serve as a brace to strengthen the follower, and to this plate is pivotally attached the clamp-bar n by two laterally-extending arms 0 0, engaging seats pp in the plate. The arms are dished or slightly concave'on their inner surface q to cause the center to stand clear of the follower, and at the end of the bar is an extension 0", which projects over the reinforced part 3 of the plate G to take the blow usually struck to release the clamp. On the lower end of the bar 12. are laterally-extending projections 25 t, which are bent up, so that their outer ends shall engage the plates a at the junction of the angles of the two surfaces where the plates are the strongest, and thus prevent the inner edge of the horizontal part of the plate bending and allowing the clamp-bar to become disengaged from the guide-plate.

To the lower end of the bar n is pivotally attached the clamp-shoe a, which is provided with tripping-toeso o, and between the toes is an inclined seat u), with which the lower end of the tripping-levery engages for engaging the clamp-shoe upon the guide-bar, and on the lower end of the clamp-shoe is a projection 2, which enters the slot f to serve as a guide to the follower D. The lower ends of the brake-shoe are inclined, as shown at z z, to cause the extremities only to bear upon the plates a to opposite the ends of the projections it, thus relieving the edges of the plates of all strain.

I am aware that angular flanged guideplates in angular grooves are shown and described in United States Patent No. 208,220, dated September 24:, 1878, and do not therefore claim anything therein shown.

Having thus fully described my invention, what I claim is 1. A file-holder provided with a grooveplate having lateral rigid projections on the edges of its embedded portions to prevent lateral displacement in the base-board.

2. A file-holder provided with a grooveplate having right-angled rigid projections on its embedded portions to prevent lateral and longitudinal displacement in the base-board.

3. A file-holder having a groove-plate provided with right-angled rigid projections on the outer edges to embed in the base-board and prevent lateral displacement therein.

4:. A file-holder having a groove-plate provided with one or more lateral rigid projec tions on opposite sides of the outer edges to embed in the base-board and prevent lateral displacement therein.

5. A file-holder having a groove-plate, in combination with a head-block provided with vertical studs to which the groove-plate is attached and having laterally-extending arms provided with projections on one of their surfaces to embed in the base-board, and prevent splitting through the groove.

6. A file-holder having a groove-plate, in combination with a head-block to which the groove-plate is attached and having laterallyextending arms provided with projections inclined on their inner sides.

7. A file-holder having a groove-plate, in combination with a head-block to which the groove-plate is attached and provided with a transverse groove in its upper surface and a curved inner side cut away on its upper surface, a follower and a clamp.

8. A file-holder having an angular grooveplate, and a follower, in combination. with a clamp having upwardly-inclined arms engaging said groove-plate, for the purpose described.

9. A file-holder having a groove-plate and a follower provided with a clamp-plate, in combination with a clamp-bar pivotally connected to the clamp-plate and engaging the grooveplate, a clamp-shoe pivotally connected to the clamp-bar, and an operating-lever pivotally connected to said clamp-bar and engaging the shoe.

10. A file-holder havinga groove-plate and a follower, in combination with a clamp-bar, a clamp-shoe connected to the bar and having tripping-toes, and a separate tripping-lever connected to the bar and engaging said toes.

11. A file-holderhavinga groove-plate and a follower, in combination with a clamp-plate connected to and extending across the follower, a clamp-bar pivotally connected to said plate and having an extension at its upper end normally engaging the plate, a clampshoe, and a tripping-lever.

12. A file-holder having a groove-plate and a follower, in combination with a clamp having a shoe provided with inclined ends e11 gaging the groove-plate as described.

13. A file-holder having an angular grooveplate and a follower; in combination with a clamp having upwardly-inclined arms engaging the under side of the groove-plate, and a clamp-shoe provided with inclined ends engaging the upper side of the groove-plate, as described.

14. A file-holder having a follower, in combination with a clamp having a shoe provided with inclined ends for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
